: This refers to the needle's thickness. Higher numbers (e.g., 31G) are thinner and typically more comfortable for insulin, while lower numbers (e.g., 21G) are thicker and used for more viscous medications. Slip Tip : The needle slides on and is held by friction
: Measured in milliliters (mL) or cubic centimeters (cc), this determines how much liquid the syringe can hold. For insulin, syringes are measured in "Units" (e.g., U-100).
